9 In a high-rise building there are 25 floors above ground floor (floor 1,
Aoor 2. ) and 6 floors below ground floor. A lift starts at floor 3 and
moves 5 floors down then 18 floors up, 4 more floors up, 26 floors down
and finally 6 floors up. At which floor does the lift finish?

Acylinder and its dimensions are shown. which equation can be used to find v, the volume of the cylinder in cubic centimeters?

Sum is 17 and their difference is 3

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
